First episode where Jax (Charlie Hunnam) is wearing his signature white on white Nike Air Force Ones.
You can tell by Tig's (Kim Coates) beard that he had started growing his facial hair after they shot the pilot and also Bobby (Mark Boone Junior) has thicker longer hair and is growing his facial hair as well. This is all due to the time lapsed between shooting the pilot and getting the go ahead and beginning to shoot the new episodes
The main character Jax (Charlie Hunnam) is partially based on specific aspects of Edward Winterhalder's life, as portrayed in his first book "Out in Bad Standings".
When Clay (Ron Perlman) arrives with the cash, Chibs can be heard saying "all about the Benjamins, baby". Tommy Flanagan who plays Chibs starred in All About the Benjamins (2002) with Ice Cube and Mike Epps.
